Embodiment 2
In conjunction with Fig. 5, Fig. 6, Fig. 7 and Fig. 8, a kind of blind wave crest plate of reduction processing cost of the present embodiment manufactures dedicated hydraulic
Machine, substantially with embodiment 1, the difference is that: the present embodiment advanced optimizes setting for upper mold 15, lower die 27 and blank holder 26
Meter, specifically: setting upper mold 15 is cavity plate, which is arranged threaded hole, and cavity plate is inserted into the screw thread by bolt
12 lower part upper die holder 14 of Kong Zhongyu top shoe is connected.The lower die 27 is punch-pin, and threaded hole is arranged along 27 length direction of lower die,
Lower die 27 is inserted into the threaded hole by bolt to be connected with sliding block 24.The upper mold 15, blank holder 26 and lower die 27 are along length
Degree direction is big globoidal structure design.
It is worth noting that inventor is not by upper mold 15, blank holder 26 and lower die in the hydraulic press initial designs
27 are designed as big cambered surface, but simple planar structure.But in practical top plate pressing process, find due to entire container top
4 length of plate is longer, often because the flowing of squeezed state plate is uneven, and causes final products obtained therefrom that warpage occurs, and extrude
Plate forming is ineffective.For this purpose, inventor begins trying upper mold 15, blank holder 26 and lower die 27, big cambered surface is set along its length
Meter is flowed with this to compensate plate.In addition, Machine Tool design experience of the inventor rich in many years, by repeatedly attempting, and simulation
Plate flow regime when suppressing blind wave 41, inventor's discovery are directed to different type of machines, the big cambered surface highest point of 26 length direction of blank holder
With a thickness of L1, the difference at minimum point with a thickness of L2, L1 and L2 is 14.2-15mm at place.Blank holder 26 is small arc in the width direction
Face structure designs, and thickness and thickness difference at minimum point are L3, L3 3.5-4.5mm at the small cambered surface highest point.This structure is set
Plate flowing is small and uniform when meter can make actually to suppress, and prevents warpage after plate forming, influences the presentation quality of plate.Specifically
Difference to the present embodiment design L1 and L2 is 14.6mm, and L3 4mm, this size is also optimal structure design.
